To Reassure and Educate Their Pregnant Patients About Changes in Their

To reassure and educate their pregnant patients about changes in their blood pressure,maternity nurses should be aware that:

A) a blood pressure cuff that is too small produces a reading that is too low; a cuff that is too large produces a reading that is too high.
B) shifting the patient's position and changing from arm to arm for different measurements produces the most accurate composite blood pressure reading at each visit.
C) the systolic blood pressure increases slightly as pregnancy advances; the diastolic pressure remains constant.
D) compression of the iliac veins and inferior vena cava by the uterus contributes to hemorrhoids in the later stage of term pregnancy.
